Digital BW, The Print

Thanks Richard for the suggestions,

Those points on the board are so close together that it going to be a supra- 
delicate job soldering to them without the points touching, but I will try to figure 
something out. I don't have anything to loose at this point.

Thanks again for clairfying these options from your experience,

John
